UNITED s'rA'ras PATENT ol-"r cai an mus 1,m. or 'Los mamas, cauronma.

r anne-SLEEVE roman city of Los An eles, county of Los Angeles,

and State of. alifornia, have invented certain new and useful Improvements in Bearing-Sleeve Pullers, of which the followin idis a specification.

y invention relates to bearing sleeve pullers, and more particularly to a simple device by means of which the bearing sleeves can be quickly and easily removed from a bearing.

vIn order to explain my invention, I have illustrated one practical embodiment thereof in the accompanying sheet of drawings, in which,-

Figure 1 is a plan view thereof, with bearing sleeve thereon;

Figure 2 is aside elevation, partly in section; and f Figure 3 is an end view thereof, partly in section on line 3-3.

Referringnow more in detail to the drawings, my invention as here embodied for illustrative purposes, comprises a tubular member, 1, provided with a handle, 2, at one end, and at its other end, rovided with a hole, 3, through its side. ounte in this hole is a stud, 4, secured to the end of a spring member, 5, attached at its other end to the inside of the tubular member 1, as at 6.

i A bearing sleeve, S, is shown on the end of the tubular member 1, as it would be ositioned during the rembval operation. hese bearing sleeves are provided with'holes, as S positioned to admit grease to'their bearings. said sleeve is also provided with a holding knob, as 5', adapted to seat in a corresponding depression in the bearing in a well known manner. Any attempt to pull the sleeve straight out by applying pull at the hole in the sleeve. tends to cause the knob S to seat more firmly in said depression and makes it diflirult without considerable power to remove the sleeve. By providing an instrument by means of which saidsleeve can be turned, the knob is easily turned out of the depression and then it can be easily pulled from the bearing. The stud 4, on the spring 5. is of such size relative to the hole 3, in the tubular member, that the strain on the stud comes against the wall of the tubular member and not on the spring 5. The position of the hole Specification of Letters Patent.

. 3, and of the stud 4, corresponds with the position of the hole S in the sleeve, that is, it 'is' positioned thesame distance from the end ofthe member 1, that the hole in thesleeveis from the end of'the sleeve. The tubular member 1 is, therefore, "inserted until it bears against the stop or inside of the bearing and then turned and as soon as said-stud comes into register with the hole S in the sleeve, it automatically moves out into said hole, as indicated in Fig. 1. It will be understood, of course, thatithe stud must be pressed inwardly as the tubular member is inserted: This is easily done by hand. The tubular member 1 can also be inserted over the shaft or axle 9 which will enter the tubular member as the tubular member enters the bearing sleeve, as will be readily understood. V

Thus I have provided a very simple, cheap and practical device for quickly and easily removing bearing sleeves from their bearlngs. It is quickly inserted and so made that the pulling stud registers circumferentially with the hole in the sleeve, and it is onlynecessary to turn the tool after it is fully inserted and the stud automatically springs out into said hole. The sleeve is givena turn and is then easily pulled from its bearing, I do not limit my invention to the details here shown except as I may be limitedbythe hereto a pended claims, for I am aware that many c anges can be made without departing from the spirit of my invention.

I claim:

1. A hearing sleeve puller comprising a member adapted to be inserted into said sleeve and having a spring pressed stud projecting therefrom and adapted to be pressed back into said member when it is inserted into said sleeve, said stud being adapted to be automatically moved outwardly through a corresponding opening in said sleeve when in register therewith, and a handle on said member for turning and pulling it with the sleeve from the bearing.

2. A bearing sleeve puller comprising a member adapted to be inserted into said bearin sleeve, said sleeve having a hole therein, said member having a stud inserted through its side a distance from its end corresponding to the distance of the hole in the sleeve from its endaa spring in said momhernorrnally pressing said stud outwardly whereby it is moved into the hole insaid sleeve when moved to register therewith, and means on said member for turning it and pulling it, substantially as described;

3. A sleeve bearing puller comprising a tubular member adapted to be inserted into a bearing sleeve having a hole through its side, said member having a hole through its side positioned from its end to correspond, with the position of the hole in said bearing sleeve, for the purpose indicated, a spring: pressed stud 1n sald hole insald member for turning tubular member and adaptedvto enter the hole in said sleeve when moved into re 'ster therewith, and a hand grip on said tu ular and pulling the same, substantially as described.
